RELATED APPLICATIONS

This application is a continuation of application Ser. No. 15/354,495filed Nov. 17, 2016, which claims the benefit of U.S. ProvisionalApplication No. 62/256,398 filed Nov. 17, 2015, each of which is herebyincorporated herein in its entirety by reference.

FIELD OF THE INVENTION

The present invention relates to infusion pumps and, more particularly,to reducing power usage in battery powered ambulatory infusion pumps.

BACKGROUND

There are many applications in academic, industrial, and medical fieldsthat benefit from devices and methods that are capable of accurately andcontrollably delivering fluids, such as liquids and gases that have abeneficial effect when administered in known and controlled quantities.Such devices and methods can be particularly useful in the medical fieldwhere treatments for many patients include the administration of a knownamount of a substance at predetermined intervals.

One category of devices for delivering such fluids is that of pumps thathave been developed for the administration of insulin and othermedicaments for those suffering from both type I and type II diabetes.Some pumps configured as portable infusion devices can providecontinuous subcutaneous medicament injection and/or infusion therapy forthe treatment of diabetes. Such therapy may include, e.g., the regularand/or continuous injection or infusion of insulin into the skin of aperson suffering from diabetes and offer an alternative to multipledaily injections of insulin by an insulin syringe or an insulin pen.Such pumps can be ambulatory/portable infusion pumps that are worn bythe user and may use replaceable cartridges. Examples of such pumps andvarious features that can be associated with such pumps include thosedisclosed in U.S. patent application Ser. No. 13/557,163, U.S. patentapplication Ser. No. 12/714,299, U.S. patent application Ser. No.12/538,018, U.S. patent application Ser. No. 13/838,617, U.S. patentapplication Ser. No. 13/827,707 and U.S. Pat. No. 8,287,495, each ofwhich is incorporated herein by reference in its entirety.

Ambulatory infusion pumps as described above typically rely on one ormore batteries to power the drive mechanism of the pump to delivermedicament. Many such ambulatory infusion pumps are programmable andinclude data storage and review features accessed through userinterfaces of the devices. Many such pumps also enable wirelesscommunications with other devices, such as continuous glucose monitorsand data storage devices, through communications protocols such asBluetooth or the like. Each of these and other features that can be apart of ambulatory infusion pumps further require power from the pumpbattery. However, in order for such pumps to be of a size to beconveniently carried by a user, there is limited space for the one ormore batteries and therefore limited battery capacity. As such, there isa need in the art for ways in which to preserve battery power whilestill enabling full functional use of such ambulatory infusion pumps.

Further details regarding some embodiments of various infusion pumpscan be found in U.S. Patent Application No. 2011/0144586, which ishereby incorporated by reference in its entirety.

FIG. 2A is another block diagram of some of the features that can beused with embodiments of the present invention. Pump 12 includes a powermanagement system that is connected to the connector port 110 thatreceives a combined data/power cable, such as a USB cable. That is, thecable has the capability of simultaneously providing electrical energyfor charging and data transmission for communications. A connectorinterface 206 supports data exchange and receives electrical powerthrough the connector port 110, and controls a connector data element208 and a connector power element 210. The device may be powered bybattery power in place of or in addition to the connector interface. Theconnector interface 206 passes data communications from the connectorport 110 through the connector data element 208 to a system bus 212. Theconnector interface 206 passes electrical power from the connector port110 through the connector power element 210 to a battery charger 214,which in turn is coupled to a battery 216 and which recharges thebattery. In one embodiment, the connector data element 208 isimplemented in the FIG. 2A device with a USB Isolation Chip ADUM4160product from Analog Devices, Inc. of Norwood, Mass., USA, and theconnector power element 210 is implemented in the FIG. 2A device with aUSB Power Isolation Chip LT3573 product from Linear TechnologyCorporation of Milpitas, Calif., USA. Those skilled in the art will beaware of alternative suitable devices.

A control processor 218 is connected to the system bus 212 and receivesthe data communications from the connector data element 208 forprocessing. The control processor controls operation of the variouselements of the pump 12 that are connected to the system bus. Thecontrol processor operates according to program instructions that may bestored in device memory 220. Program instructions may be stored inprocessor memory incorporated in the control processor 218. The controlprocessor also stores data from its operations in the device memory 220.The control processor 218 controls a data communications element 222that may comprise a receiver/transmitter for wireless RF communications,such as “WiFi” communications or “Bluetooth” communications between theportable device 100 and compatible external systems and networks. Thepump 12 includes an output/display element 224 such as a touchscreendisplay, operating buttons or switches, and the like. The pump 12includes a drive/pump element 226 such as a pumping mechanism fordelivery of fluid such as insulin via outlet port 54. To meet industrystandards and governmental regulations, the connector data element 208and the connector power element 210 are both electrically isolated fromthe other device components, so as to provide a device that can besafely connected to the power source and the patient at the same time.

The memory 220 of pump 12 may be any type of memory capable of storingdata and retrieving that data for transfer to one or more othercomponents of the device, such as the control processor 218. Memory 220may comprise one or more of a Flash memory, SRAM, ROM, DRAM, RAM, EPROMor dynamic storage. Memory 220 may be coupled to the control processor218 and may be configured to receive and store input data and/or storeone or more template or predetermined fluid delivery patterns. Forexample, the memory can be configured to store one or more personalized(e.g., user defined) delivery profiles, such as a profile based on auser's selection and/or grouping of various input factors; pastgenerated delivery profiles; recommended delivery profiles; one or moretraditional delivery profiles, e.g., square wave, dual square wave,basal and bolus rate profiles; and/or the like. The memory can alsostore user information, history of use, glucose measurements,compliance, an accessible calendar of events, and the like. In someembodiments, the memory 220 of pump 12 may have a data capacity of up toabout 10 GB, more specifically, up to about 3 GB, even morespecifically, about 1 MB to about 200 MB. In some embodiments, thememory of pump 12 may be up to about 3 GB, more specifically, up toabout 500 MB, and even more specifically, about 200 kB to about 200 MB.The embodiments depicted in FIG. 2 and FIG. 2A are not to be consideredmutually exclusive, rather, components depicted in either may beinterchanged between embodiments. Referring to FIG. 3, a front view ofpump 12 is depicted. The pump 12 may include a user interface, such as,for example, a user-friendly GUI 60 on a front surface 58 or otherlocation of pump 12. The GUI 60 may include a touch-sensitive screen 46that may be configured for displaying data, facilitating data and/orcommand entry, providing visual tutorials, as well as other interfacefeatures that may be useful to the patient operating the pump 12. TheGUI can also present alarm or alerts to the user.

Referring now to FIG. 4, a system 100 according to embodiments of thepresent invention includes a medical device such as an insulin pump 12having a wireless connection 104 to a mobile phone 102, such as asmartphone, via, for example, Bluetooth, Bluetooth low energy, mobile orWi-Fi communications. Wireless connection 104 is established viatransmitter/receiver 32. In some embodiments, the phone 102 can alsohave a wireless or wired connection 106 to one or more other nodes 108,such as a cloud storage service means, a blood glucose meter 108 or acontinuous glucose monitor (CGM). Although the system 100 is describedwith respect to a mobile phone, alternate types of devices could be usedin place of a phone as the device 102, including, for example, anelectronic tablet or a laptop or desktop computer. Similarly, althoughdescribed with respect to an insulin pump, the medical device 12 can beany other type of programmable medical device capable of wirelesslycommunication with a mobile phone 102 or other device, including, forexample, infusion pumps for infusing medicaments other than insulin.

In embodiments wherein node 108 comprises a cloud storage service meansfor receiving data from phone 102 regarding pump 12, it is especiallydesired to conserve battery life of both pump 12 and phone 102. Phone102 may comprise a master device, and pump 12 may comprise a slavedevice, such that phone 102 initiates and controls the transmission ofdata between phone 102 and pump 12, via, for example, Bluetooth or otherwireless means. Phone 102 may include a program or applicationconfigured to receive and/or transmit data, instructions and/or otherinformation between pump 12 and phone 102. Although pump 12 and phone102 may be in constant or near-constant communication in an attempt toprovide real-time feedback, such an arrangement may negatively impactbattery life of both pump 12 and phone 102. Therefore, variousembodiments herein provide improved methods of communication betweenpump 12 and phone 102 to prolong battery life of both devices.

Pump 12 may, for example, be configured to transmit Bluetoothadvertising packets via transmitter/receiver 32, each packet containinga number of bits of information. Phone 102, via the Bluetooth connection104, is configured to detect and receive the advertising packetstransmitted by pump 12.

In some embodiments, the frequency of communications between pump 12 andphone 102 to transmit data may be modified to conserve battery power ofone or both devices. In one embodiment, the frequency of communicationsmay be event-based. For example, the event may comprise delivery of abolus, change in basal delivery rate, triggering of an alarm or otherpredetermined event. Upon occurrence of such a predetermined event,processor 42 of pump 12 is configured to modify the contents of its nextBluetooth advertising packet to include an indication based on the eventthat phone 102 should initiate communication with pump 12 to transmitdata regarding the event. This allows pump 12 to remain in a lowerpower, advertising state until phone 102 initiates communicationresulting in pump 12 and phone 102 being paired. In one embodiment, alist of predetermined events is stored in memory device 30 of pump 12.In another embodiment, processor 42 includes programming having a listof predetermined events.

In another embodiment, each Bluetooth advertising packet from pump 12may be configured to include an indication of pump status. Uponoccurrence of a predetermined notable event requiring a data transferbetween pump 12 and phone 102, the indication of pump status included inthe Bluetooth advertising packet from pump 12 signals phone 102 toinitiate communication with pump 12 to transmit data regarding theevent.

In another embodiment, the frequency of wireless communications may beevent-based but the amount of data transmitted varies according to thenature of the event. For example, for any events predetermined to be ofa less important nature, pump 12 may transmit an indication to phone 102that a data transfer is required at a later time when pump 12 isconnected to an external power source via connector port 110 forrecharging. For any events predetermined to be of a more importantnature, pump 12 may transmit an indication that a data transfer isrequired immediately to transmit data regarding the event. Therelationship between the nature of an event and the amount of data to betransmitted may be stored in memory device 30 or included as part ofprogramming operable by processor 42.

In another embodiment, the frequency of wireless communications may beperiodic, or time-based. For example, pump 12 may transmit an indicationto phone 102 at predetermined intervals that a data transfer isrequired. Such intervals may comprise every 15 minutes, every 30minutes, every 60 minutes, or any other desired interval. Contained inthe periodic indication will be information regarding the pump,including for example basal rate, delivery of last bolus, any eventsthat have occurred since the last data transmission, or otherinformation stored by the pump. The frequency of wireless communicationsmay be stored in memory device 30 or included as part of programmingoperable by processor 42.

In another embodiment, wireless communications between pump 12 and phone102 may comprise only a partial subset of all available information.Pump 12 may transmit an indication to phone 102 that a data transfer isrequired, and upon initiation of the data transfer only transmit apartial subset of all available information stored by the pump. Whenpump 12 is connected to an external power source via connector port 110for recharging, pump 12 transmits an indication to phone 102 to transferall available saved data regarding pump 12. The data selected to becontained in the partial subset may be based on information stored inmemory device 30 or included as part of programming operable byprocessor 42.

In another embodiment, wireless communications between pump 12 and phone102 may be proximity-based. For example, phone 102 may rely on GPSinformation to initiate data transfer from pump 12 such that if apatient having phone 102 arrives at a specific location such as ahospital, clinic or other care facility, phone 102 may determine throughGPS information that a complete data transfer is required from pump 12in order to have the most current data available on phone 102 when thepatient visits their care provider. A list of locations for full datatransfers, and/or relationships between locations and the amount of datato be transferred, may be stored in memory device 30 or included as partof programming operable by processor 42.

In another embodiment, it is also desired to prolong battery life ofphone 102. For example, when transferring information from phone 102 tonode 108 such as a cloud storage service means for receiving data fromphone 102 regarding pump 12. In one embodiment, transfers from phone 102to node 108 are delayed until the cellular connection of phone 102 meetsa predetermined minimum signal strength, or until phone 102 is connectedto a wi-fi network, at which time data saved on phone 102 is transmittedto node 108.

In another embodiment, data transfers from phone 102 to node 108 onlyoccur when the user of phone 102 first launches the application whichcontrols data transfers, and/or only when the user is actively using theapplication. In another embodiment, data transfers from phone 102 tonode 108 only occur when phone 102 is connected to a power source and isbeing recharged.

In another embodiment, data transfers from phone 102 to node 108 areevent-based, such data transfers are delayed until a predetermined eventhas occurred. Alternatively, data transfers may be delayed until apredetermined number of events have occurred. Alternatively, datatransfers may be event-based but the amount of data transferred variesaccording to the nature of the event. For example, for eventspredetermined to be of a less important nature, the data transfer fromphone 102 to node 108 may be delayed. Whereas events predetermined to beof a more important nature cause phone 102 to transfer data to node 108upon occurrence of the event.

In another embodiment, data transfers from phone 102 to node 108 may beperiodic, or time-based. For example, data transfers may occur atpredetermined intervals such as every 15 minutes, every 30 minutes,every 60 minutes, or any other desired interval.

In another embodiment, data transfers from phone 102 to node 108 may beproximity-based. For example, phone 102 may rely on GPS information toinitiate the data transfer such that if a patient having phone 102enters a hospital, clinic or other care facility, phone 102 maydetermine through GPS information that a complete data transfer isrequired to node 108 in order to have the most current data available onphone 102 when the patient visits their care provider. The abovedescribed embodiments regarding conserving battery life of both pump 12and phone 102 may be combined if desired. For example, the frequency ofcommunications between pump 12 and phone 102 to transmit data may beevent-based and time-based. Or, for example, one or more embodiments forconserving battery life of pump 12 may be combined with one or moreembodiments for conserving battery life of phone 102. Other suchcombinations of energy-saving methods described herein are within thespirit and scope of the invention.

Although embodiments described herein may be discussed in the context ofthe controlled delivery of insulin, delivery of other medicaments,singly or in combination with one another or with insulin, including,for example, glucagon, pramlintide, etc., as well as other applicationsare also contemplated.
